RESUMO

The Restricted Three Body Problem predicts the existence of the several families of periodic orbits in the Earth-Moon System. In this work, we studied two of them the Family G of direct periodic orbits around the L1 and the Family H2 of direct periodic orbits around the Moon. Our investigations considered, besides the Restricted Three body Problem, the Four Body Problem Sun-Earth-Moon-probe added of the due disturbances to the terrestrial oblateness and the pressure of solar radiation. Then, from the Family Gs orbits, we defined two groups of paths that form links among the Earth and the Moon, whose characteristics allow transfers among terrestrial and lunar orbits of low altitude and large inclinations, and a route of escape of the System Earth-Moon. Already starting from Family H2s orbits, we defined a group of stable paths around of the Moon and another that forms routes of escape and capture of the Moon through L1 e L2.
